SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 589,653, dated September 7, 1897.

Application tied May 29,1897, semina 633,756. momia.)

To all whom it iii/ty concern,.-

Be it known that I, RICHARD A. HAEGELIN, of St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and Improved Sash-Lock, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved sashlock designed for use on windows of houses, railroad-cars, and the like, and which is simple and durable in construction an d arranged to conveniently and securely lock the sash at the ends or intermediate points of its travel to prevent rattling of the sash andto support the same equallyT at both sides.

The invention consists principally of bolts adapted to engage with their free ends the window-frame, toggle-levers connected with the said bolts, and a device for opening and closing the said toggle-levers to move the said bolts from or toward each other and carry their free ends into or out of engagement with the window-frame.

The invention also consists of certain parts and details and combinations of the same, as will bel fully described. hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings` forming apart of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation oi' the improvement as applied. Fig. 2 is a similar view of the saine with the covers removed. Fig. 3 is a sectional plan view of the same on the line 3 of Fig. 1, and Fig. l is a perspective view oi' a modified form of the screw-rod.

The improved sash-lock is preferablyfarranged on the lower cross-bar of the sash A, fitted to slide in theusual manner in suitable guideways arranged in the window frame or casing B. The latter is adapted to be engaged by friction-rollers C and C, journaled on the outer ends of bolts D and D', respectively, held to slide longitudinally in suitable recesses formed in the cross-barof the sash A, as plainly indicated in Fig. 2. The inner ends of the bolts D and D are pivotally connected wit-h pairs of toggle-levers E E', connected with each other by links E2 and E3, formed with apertures having right and left hand screw-threads engaged by the corre spending screw-threads F and F', formed on a screw-rod F2, mounted to turn at its lower end in the bottom ot a. casing ll, set in the cross-bar of the sash and containing the said toggle-levers and screw-rod, as plainly indi cated in Figs, 2 and 3. The casing ll is closed by a cover P12-and similar covers ll2 close the recesses in, which the bolts D and D' operate. The upper end of the screw-rod F2 extends through the top of the casing ll and the flange of the cover ll", and on the outer end of the said screw-rod is formed a handle in the sh ape of a knob F3, adapted to be taken hold of by the operator to turn the said screw-rod, so as to move the links E2 and lli simultaneouslyvv toward or from each other to move the bolts D and D' outward or inward and carry the friction-rollers C C' in and out of engagement with the window casing or frame B. Thus when the knob Fi is turned in one direction Athe toggle-levers are opened to dra w the bolts D and D' inward, and when the knob is turned in the opposite direction the toggle-levers are closed to push the bolts D D' outward, so as to engage the friction-rollers with the window-Casin g to lock the sash in place in whatever position it may be in, either at the ends of its travel or at intermediate points of said travel, as the case may be.

lf desired, the knob F3 can be dispensed with, and in this case the screw-rod F4 is provided at its upper end with a recess F5 for engagement by a suitable key carried by the operator for turning the screw-rod in the desired direction to lock or unlock the sash, as the case may be. Now it will be seen that by the arrangement described the frictiow rollers C and C' can be moved with more or less force in contact with the window-casing to lock the sash in position, or on slightly relea-sing the pressure of the bolts the sash can be lowered at any desired rate oi speed by its own gravity, and if the sash is to be raised the bolts D and D' are caused to move inward toward each other tov completely move the friction-rollers out of engagement with the wi-ndow-casing.

The device is very simple and durable in construction, is not liable to get out of order, as no springs or the like are employed and positive movement is given to the various parts.

on turning the screw-rod, substantially as shown and described.

2. The Combination of two bolts, two toggle-levers respectively connected to the bolts and a differentially-threaded screw eoaet-ng with the toggle-levers whereby to throw or withdraw the bolts upon the operation of the :o

screw.
